Our Technology
Geothermal is a heat energy from the earth. Geothermal energy is a clean and renewable energy source, with no greenhouse gas emissions, making it a more environmentally friendly alternative to fossil fuels. Geothermal energy created from the heat generated by the earth's internal core and is available 24-hours a day, 365 days a year.
GeoAgni is the closed-loop low-heat geothermal concept which is a subset of geothermal power generation technology that use a closed-loop system for the circulation of a heat transfer fluid. Unlike open-loop geothermal plants that directly extract geothermal fluids from the Earth.
GeoAgni geothermal concept keep the heat transfer fluid contained within a closed circuit, minimizing direct interaction with underground geothermal reservoirs by using engineered and high efficiency heat transfer fluid media in the circulating system.
Our GeoAgni closed-loop geothermal plant is revolutionize the renewable energy sector by providing a consistent and stable resource base (24/7 Based Load), providing with long-term, energy reliable and energy security with no requirement of fuel and raw material suppliers while minimizing environmental impact.
With the new concept of closed-loop low heat systems, scalability of this system can be exponentially performed for industrial power plants, also providing heating and cooling applications.
Closed-Loop
Geothermal Power Plant
Why Closed-Loop ?
Heat Exchange System
Closed-loop geothermal power plants consist of a network of pipes filled with a heat transfer fluid (commonly a water and antifreeze mixture). This fluid circulates through the closed-loop system, allowing it to absorb heat from the Earth and transport it to the surface.
Heat Extraction
The heat transfer fluid circulates through a series of underground heat exchangers. These heat exchangers are typically installed in deep boreholes. As the fluid passes through these exchangers, it absorbs heat from the surrounding rock or fluid reservoirs.
Heat Pump and Power Generation
Once the heat transfer fluid reaches the surface, it is used to heat a working fluid, such as a refrigerant, in a heat pump. The heat pump then transfers the heat to a power cycle (e.g., organic Rankine cycle or binary cycle) to generate electricity. This process is similar to how traditional geothermal power plants operate, except that the heat transfer fluid is isolated in a closed circuit.
Recirculation
After transferring its heat to the power cycle, the heat transfer fluid is returned to the underground heat exchangers to continue the cycle. This recirculation allows for the continuous extraction of heat from the Earth.
High-Efficiency Heat Transfer Fluids
This is the one of the key GeoAgni technology which is essential in geothermal power plant system. These fluids are designed to have and high performance in transferring heat. Some common characteristics of high-efficiency heat transfer fluids include high thermal conductivity, wide temperature range, low viscosity, stability and longevity, low freezing point, high boiling point, non-toxic and environmentally friendly and compatibility.
GeoAgni Advantages
01 Environmental Friendliness
They have a minimal impact on the environment, as they do not alter the temperature or flow of underground reservoirs and are less likely to cause subsurface disturbances.
02 Predictability and Reliability
Closed-loop systems are more reliable because they are not as sensitive to changes in the geothermal resource. This makes them suitable for a broader range of locations.
03 Scalability
They can be designed for various scales, from residential and small commercial applications to larger power generation facilities.
04 Lower Environmental Permitting Requirements
Due to their closed-loop design and reduced impact on geothermal resources, permitting requirements may be less stringent compared to open-loop geothermal plants.
05 Sustainable
GeoAgni closed-loop geothermal power plants are a sustainable and environmentally friendly way to harness geothermal energy for electricity generation and heating and cooling applications.
